hi!
i have to read numeric data from the yokogawa wt3000 via labview.
reading value is no problem, but i became with my program the values from the wt3000 delayed.
i choose 500ms update rate for my measurement.
thank you!

I am really unsure what you are asking. Could you provide some details? Attaching your code would help.

that's my code
09-06-2013 03:15 PM
the front panel of the program

You have not posted any code and you have not posted any details on what the actual problem is.

i chose for my while loop a time of 100 ms, but in truth the while loop takes more than 100ms.
i want to read the data from yokogawa in real-time, without delay.
thank you for your replay, and sorry for my bad english

The wait (ms) timers you are using specify a minimum time of 100 ms, not a loop time of 100ms.

It the instrument is taking longer than 100ms, a msec wait is not going to force it to run faster. You've programmed it for an update rate of 500ms. Is that the fastest it can be set? If so, you have an instrument limitation. Read the manual.
Mentioning "real-time" and "without delay" is meaningless. If 500 msec is the sample rate you have set if for and that is how fast you are acquiring, that in fact is without delay and as real-time as you can get.

hi!
thank you for your replay.
for the update rate of yokogawa WT3000 i can choose between:
<Time> = 50, 100, 250, 500 (ms), 1, 2, 5, 10, or
20 (s)
for example, when i take 500ms update rate the wt3000 update the data each 500ms.
that's not the problem, the problem is, when i run my labview programm, the time for one while loop takes more than 500ms, it takes 800ms.
so i get the data from the WT3000 delayed.
i hope you know what i mean.
thank you!

Well, you still have not posted any code. Be sure to include subVIs.
